T all '1U/rom .it may concern.'

Be it known that I, SANFORD D. LE CLAIR.,

a citizen of the United States, residing at San F ranoisco, in the county of San vF rancisco and State of California, have invented new and useful Improvements in Scrapers, of which the following is a specification.

The object of the present invention is to provide an improved form of scraper for excavating operations, which will be simple and economical inconstruction, durable in use, having no loose parts liable to get out of order, and elii'cient in operation.

In the accompanying drawing, Figure 1.

is a perspective view of my improved scraper looking from the front; F 1g. 2 is a sectional view on the line 2 2 of Fig. 1;

. tached; Fig. 7 is a broken simil ar halves.

effected either Fig. 3 is a. cross-sectional view of a modified form of the scraper; Fig. 4 is a similar view of a further modification; Fig. 5 is' a view, similar to Fig. 2, of uniting the two halves of the scraper; F ig. 6 is a broken'perspective view of one of said halves in the latter constructn, de-

perspective view of a further modification.

Referring to the drawing, lpindicates my improved scraper, preferably made of two Each half is' formed from a sheet metal blank having two parallel longer sides,the blank being bent through a little more than a right angle along a eentral line parallel with, and midway between, said sides. Ends of the two pieces are then united so as to extend from each other substantially at vright angles, said union being by riveting over-lapping ends, as shown at 2 in Fig. l, or bending inward said ends to form flanges 3, and

riveting said flanges together, as shown at 4 in Fig. 5. Saidends thus united are perforated to receive a ring 6 to which is attached a real' cable 7. The front ends have ca'ch a series of perforations 8, through any desired perforations in which series ,can be passed rings 9 connected to an ext( riding forwardly cable 10 which passes loosely through an eye l1 of a union l2, lto another eye of which is secured a forwardly extendingeable 13.

In use the cable 13 is wound around a drum rotated by a suitable engine andthe showing a different method i cable passes around an idle pulley and is also operated byhsaid engine. The scraper is thus self-regulating, for, when the cable 13 first advances, the learth which is scraped from the'surface of thevground collects on the lower portion of the scraper and presses it downward into the ground, so that more and more earth is scraped thereby, until the scrapings reach the level of the upper portion of the scraper.` When it has been completely filled, and a suliicient quantity of earth is being conveyed thereby, the pressure on the upper portion of the scraper prevents it digging into the ground and the scraper can rideeasily over the surface of the ground to the point of destination. The degree to which the scraper tends to dig into the ground can be varied by properly selecting the holes in the front end of the scraper to which the cable 13 is attached. When the scraper has arrived at the place to which the earth is desired .to beeconveyed, tension is removed from the cable 13 and applied to the cable 7,,and the scraper is drawn backward, immediately leaving its load, and traveling easily 'over the surface to the pointv from whichit originally started.

In the modificationl of my invention shown in Fig. 7 I may attach to the scraper at theapex or juncture of the two halves a cutter 18, formed of pieces of sheet metal, riveted together as shown at 19, and riveted as shown at to the scraper. Said cutter tends to cut and break up clods or lumps of earth. l f

Instead of bending the sheet metal of each half at a sharp angle, it may be bent in a curve as Ashown at 21 in Fig. 3, or the central portion of the half may be flat as shown at 22 in Fig. 4.

I claim-:-

-1. A scraper consisting of two like halves secured together at their rear end and extending divergently forward, each half com prising upper and lower diverging portions extending both inwardly and forwardly.

2. A scraper, the sides of which extend divergently forward, each side consisting of a substantially V-shaped piece of metal,the sides of which extend divergently forward and respectively upward and downward.

3. A scraper, the sides of which extend divergently forward, each side consisting of In testimony whereof I have herennto set a substantially V-shaped piece of metal, the' myhand n the presence of two subscribing sides of which extend divergently forward witnesses.
